To all whom it may concern.' y

Be it known that we, Vi-:RN SLA'i'icR and Lnoxioiis D. lViisT, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and usetul Improvements in `Fume-Dissemiiiators; and we do declare the following tobe a t'ull, clear, and

exact description otl the invention, such as will enable others skilled in the art to which it appertains to make and use the saine. y

Our invention relates to improvements in l'attachments t'or treating a forced flow of air with a suitable liquid agency, and dit'- ,fusing the saine laden with moisture taken up from said treat-ing agency, the object thereof bei-ng to provide a comparatively simple and inexpensive device of this class which will be highly efficient and adaptable to a wide range otl uses.

lVith this general object in view, thev invention 'resides in certain novel features of consti'iictioii and in unique combinations of pai-ts to beI hereinafter fully described and claimed. the descriptive mattei' being supplemented by the'accompanying drawing which constitutes a part of this application, andin which:

Figure 1, is a view in side elevation and partly in section, of an air delivery casing, showing our invention applied thereto; Fig.

2, is an enlarged vertical sectional view,

taken longitudinally through the improved attachments; Fig. 3, is `a verticalsectional view, taken transversely in the plane of the line 3-3 of Fig. 2; and Fig. 4, is an'enlarged longitudinal sectional view through the detached absorbent moistening element and its metallic gauze support.

In specifically describing the structure shown in the drawing similar characters will be employed to designate corresponding parts throughout the several views, and reference will be herein made to the immerous elements by theirvrespective indices. To this end the numeral 1 designates a suitable base from which a casing 2 rises, said base having mounted thereon a-motor 3 which drives a rotary centri't'ugally delivering fan -1 for drawing air into the casing 2 at the upper end thereof and for discharging such air through an outlet nipple 5, to which is suitably connected the larger end of a Atruste-cone-shaped nozzle 6, the outer smaller end of which may be coupled up, when desired, with a suitable fiexible tube, as indicated iii dotted lines in Fig. 1.

Mounted in the nozzle G and held therein by frictioiial engagement therewith, is an absorbent member 8 which is adapted to be saturated with the treating `liquid used, said member being composed of' a hollow frusto-cone-shaped body 9 formed of wire gauze, and a covering 10 of any suitable absorbent material such as cloth or felt, open me a goods being preferably employed in constructing,r said covering. The wire gauze 9 serves not only to retain the pad or 'absorbent covering 10 in proper position within the nozzle. 6, but said gauze is resilient to ahigh degree and thus the entire member 8 will be held iii yieldingfrietional contact with the interior surface of Said nozzle. This permits removal of said member S when necessary but it will otherwise be effectively heldin operative position.

For supplying the liquid to the member 8, a reservoir 11 is provided, such reservoir being preferably in the form of an inverted ing being threaded in a boss on the upper side ot' the nozzle The bore through the casing 13 is preferably of rather small diameter and the passage ot' liquid therethrough may be accurately controlled by means of a needle valve l-l.. For permitting air to enter the reservoir 11, thus allowing the liquid to escape therefrom. an upright tubel5 preferably rises through the cap 12 as shown.v A screw cap 1G is shown applied to the projecting lower end of tube 15 and it" the threaded connection between the two be suflieiently loose, loosening oi said cap will permit the. necessary amount of air to enter the reservoir. Y[luder other conditions, however, it will be necessary to remove .the cap 16, but it may be applied and tightened whenever necessary to prevent the entrance of air into the reservoir. thus insuring that the contents of the latter be 'not unnecessarily evaporated.

In filling the reservoir 11, the nozzle 6 will be detached from the nipple 5 and the entire device will be inverted to dispose the open end of said reservoir upwardly. The cap may now be easily nntlireaded from the reservoir 11 to permit filling thereof and said cap -will be again applied, after which Willibe supplied by the absorbent member 8 in greater or less quantity according to the manner in which the value lt is set, said valve being also capable of cutting oif the entire supply when required, and a current of air being discharged from the casing Q, in passing through the nipple 5 and nozzle 6, it will become laden with inoisture exuded from the liquid with which the member 8 is saturated.

In spite of utmost cleanliness and sanitation, the atmosphere in rooms in which a number of persons are assembled has a close oppressive odor, and while not so perceptible to the constant occupant, it is quite unpleasant to a new arrival from the'ffresh air. Such disagreeable conditions m'ay be readily overcome by impregnating the air in the room with a pleasant fragrance if perfume be employed in the reservoir l1.

The arrangement is also Vof great advantage in supplying medicated air in sick rooms and in perfuming or deodorizing the air in such rooms, and while we have termed our attachment a fume disseminator, in the latter uses just mentioned it will be apparent that fumes, in their technical sense of noxious gases, are not generated, as would be the casein fumigation proper.

From, the foregoing, taken in connection 'with the accompanying drawing, the construction, usesand advantages of the invention will be readily understood, but in conclusion we will state that although we have shown and described certain specific details for illustrative purposes, numerous changes may be made within-the scope of the inven tion as claimed without sacrificing the main characteristics thereof.

Olbviously the liquidl from the lreservoir mensioned Jto snugly fit within said nozzle,y

said member comprising a hollow body of wire gauze prov1ded with a covering of absorbent material held in yielding frictional contact with the interior tapering surface of said nozzle by the resiliency of the wire gauze, a alved conduit element carried by said nozzle and con'nnunicating with said absorbent member therein, and a reservoir supplying said conduit with a.. suitable saturating liquid for said absorbent member, substantially as described.

In appliances of the character set forth, the combination with a portable casing having an air inlet and an air outlet together with an associated rotary blower, of a nozzle, provided with a hollow tapering body portion, adapted to be connected with said air outlet, an air moistening clement formed and dimensioned to snugly fit within said nozzle, said element comprising a hollow tapered foraminous support enveloped with a covering of absorbent material, a valve controlled feed conduit leading to said moistening element, through an aperture in said nozzle body, and a reservoir, `carried by and communicating with said valved conduit element, for supplying a controlled flow of a suitable liquid to said absorbent material,

substantially as described.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.
